Application mea november 22, i917. serial No. 203,402.

To all fui/71,0222, it may concern Be it known that l, CARL Hanan, Jr., of Baltimore, in the State of Maryland, have invented a certain new and useful Improvement in Furnaces, and do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to furnaces adapted to be used for many different purposes, but

it is applicable especially to furnaces used for drying or baking distillery waste or slop.

The object of my invention is to provide a furnace of an advantageous character and which is so arranged as to distribute the heat effectively therein.

A further object of my invention is to provide a furnace arranged to distribute the heat uniformly therein and which 'is heated by oil burners located at one end of the furnace.

Further objects of my invention will appear from the detailed description thereof contained hereinafter.

While my invention is capable of embodiment in many different forms, for the purpose of illustration l shall describe only one form of my invention in the accompanying drawings, in which- Figure in accordance with my invention;

Fig. 2 is a vertical section of the main portion of the same;

Fig. 3 is a part elevation and part transverse section of the same;

Fig. 4 is a longitudinal vertical section, showing the arrangement of the oil burners at one end of the furnace;

Fig. 5 is a transverse vertical section of the same;

Fig. 6 is an end elevation, showing the location of the oil burners; and- Fig. 7 is an end elevation, showing one of the cars adaptedto convey the material to be heated into the furnace.

ln the drawings, l have shown a plurality of air-blast oil burners 1, located in openings 2 in a front wall 3, communicating with a downwardly-inclined passageway 4. The passageway 4 communicates with a lon'- gitudinal passageway 5, located between the sides of two walls, having a cover plate 7 for example of sheet iron, and a lower lining 8. rlhe iron plate 7 .is provided at internals with a plurality of openings 9, which increase in size from the 'used for receiving the distillery 1 is a plan view of a furnace made inlet endV of the passageway 5 to the outlet end thereof, the purpose an increasing amount of the products of combustion from the passageway 5 to the space above plate 7, so as to bring about a uniform distribution of the heat therein.

At intervals along` the passageway 5 there are provided a plurality of pillars 10, which support the plate 7 and provide an adequate support for a pair of rails 11, carrying cars 12. Each car 12 has a number of raclrs13, supported upon uprights 14, so as to receive a plurality of pans or trays 15, which are waste or slop to be dried or baked. The space above the plate 7 is inclosed with side walls 16 and a roof 17. At the two ends thereof there are located, respectively, pairs of swinging doors 18 and 19. Products of combustion from the oil burners 1 pass from the passageway 4 into the chamber 5, and thence through the openings 9 into proximity to the cars 12, after which they pass out through a pipe 20, which leads out through the roof 17, and then downwardly to an exhaust fan 24, driven byV any suitable source of power, through the agency of a pulley 25 connected to said fan. The products of combustion are exhausted pipe 26, which leads to a stack 27.

lfn the operation of my invention, a plurality of the cars 12, having been provided with pans 15 filled with the distillery waste or slop, are run into the furnace on the tracks 11 and 'the doors 18 and 19 are closed. Meantime, the furnace will have been heated by the series of oil burners, from which products of combustion pass forwardly through the passageway 4 an chamber 5 and through the openings 9. Be cause of the progressive increase in size of the openings 9, the uniform manner. The products of combustion, after v leaving the cars 12, pass out through the pipe 20V to the fan 24, out through the stack tinued in this manner until the material in the pans 15 has been dried or baked to the desired extent. Thereupon thev doors 19 are opened and the cars 12, carrying the material which has been completely subjected to the heat treatment', are drawn out of the furnace. The doors 19 are then closed and the doors 18 opened to introduce additional cars to take the place of those removed,

being thereby to admit from the fan 24 through a 27 The heating is conllIlO whereupon the doors 18 are closed and the heat treatment continued. In this way, the heating of the .material may be carried on progressively and in a substantially continuous manner. At the same time, the *heat treatment will have been substantially uniform, so that the material in the pans 15 will not have been subjected to any excessive degree of heat.

While I have described my invention above in detail, I Wish it to be understood that many changes may be made therein Without departing from the spirit thereof.

I claim: l

l. A furnace having a heating chamber, substantially level rails extending therethrough and means for heating the chamber comprising a conduit for the hot products of combustion belowA the heating chamber, the inlet. end of which is downwardly-inclined, and means for uniformly distributing the heated products of combustion in said heating chamber.

2. A furnace having a heating chamber, substantially level rails extending therethrough, and means ber comprising a conduit forA the hot prodfor heating the chamucts of combustion below the heating cham ber, the inlet end of which is downwardly inclined, a plurality of openings for uniformly distributing the heated products of combustion in said heating chamber and a fan at one end of said heating chamber for withdrawing the products of combustion.

3. A furnace having aheating chamber, rails extending therethrough, means for heating the chamber for the hot products of combustion below the heating chamber, the inlet end of which is downwardly inclined, a series of oil burners at one end of said conduit and a plurality of openings of progressively increasing size so disposed in the bottom only of said heating chamber as'to uniformly distribute the heated products of combustion rin said heating chamber.

that I claim the foregoing set my hand.
